HOK, now known as Populous, made this sketch of what the dome could look like.

The 5-2 vote enacts a resolution tabled in March because the BJCC didn't have the funds to proceed with the 57,500-seat multi-use facility, which would include extra convention space enabling the complex to attract more conventions, trade shows, sporting events and concerts.

Populous -- formerly known as HOK -- has won the right to design the facility.

On Tuesday, the Birmingham City Council authorized a proposal by Mayor Larry Langford to set aside $8 million a year to begin the design phase of the BJCC expansion. Langford told the board that he has been approached by several companies interested in paying $1 million a year for stadium naming rights.

The BJCC board said it plans a ground-breaking at 5 p.m. Tuesday at the site of the dome, which would be located adjacent to a proposed entertainment district along Richard Arrington Boulevard between 22nd Street North and 24th Street.
